A few things Stream doesn’t yet support are external access (outside your organization), video playlists (either shared or personal), and, regardless of its name, live streaming. Stream should also not be mistaken for a learning management system; its feature set will generally not meet your LMS needs.

Stream will soon fully replace Office 365 Video, which is why you don’t see Video on this infographic. For that reason, it’s recommended to use only Stream moving forward. Microsoft states it will be performing the migration of videos from Office 365 Video to Stream in the background, though there is no published timeline nor details on how it plans to deal with duplicate content or portals with identical names.
